H3C S9800-G Series Next‑Generation High Density Data Center Switch

The H3C S9800-G Series Data Center Switch is a next-generation high-performance Ethernet switch tailored for premium data centers and AIGC intelligent computing scenarios. Designed to meet the demands of large-scale server access, high-bandwidth data transmission, and low-latency workflows, this series integrates dense 400GE/200GE/100GE port configurations, enhanced SDN programmability, lossless RoCE network support, and enterprise-grade security. Available in multiple models (including S9820-8C-G, S9855-24B16DH-G, and S9825-64DH-G), the S9800-G Series serves as a core or aggregation layer switch in modern data centers, seamlessly connecting to H3C S12500/S9800 series switches via 400GE/800GE uplinks while providing high-density access for servers and GPU clusters.

400GE / 800GE High‑Speed Port Performance

The H3C S9800-G Series stands out with exceptional port density and scalability, addressing the needs of ultra-large data centers for non-blocking server access. The series supports a wide range of port configurations, including up to 64x400GE QSFP112 ports, 128x200GE QSFP56 ports, or a mix of multi-speed ports (10GE/25GE/40GE/100GE/200GE/400GE/800GE). Modular models like the S9820-8C-G and S9825-8C-G feature 8 pluggable slots, compatible with 200G/400G/800G line cards, enabling flexible port upgrades as network demands evolve. Fixed-port models such as the S9855-24B16DH-G (24x200G + 16x400G) and S9825-64DH-G (64x400G) offer out-of-the-box high-density connectivity, ideal for rapid deployment in cloud and AIGC data centers.

RoCE Lossless Network & AIGC Cluster Optimization

Optimized for high-performance computing (HPC) and AIGC workflows, the S9800-G Series fully supports RoCE (RDMA over Converged Ethernet) v1/v2 protocols, enabling lossless network deployment with zero packet loss and ultra-low latency. The switch integrates advanced features including PFC (Priority-based Flow Control), ETS (Enhanced Transmission Selection), DCBX (Data Center Bridging Exchange), and ECN (Explicit Congestion Notification) with auto-threshold adjustment, ensuring stable and efficient data transmission for latency-sensitive applications. Additionally, it supports flexible global load balancing (FGLB) and data plane self-healing (DPSH) capabilities, enabling microsecond-level traffic switching and optimal link load distribution across the entire network.

Spine Leaf Architecture Compatibility

Equipped with industry-leading programmable switching chips, the H3C S9800-G Series offers powerful SDN capabilities to adapt to dynamic network evolution. It supports standard Netconf, Python, and Ansible automation frameworks, allowing users to customize forwarding logic and deploy new features via simple software upgrades—eliminating the need for hardware replacement. The switch also provides comprehensive network visualization through ERSPAN, gRPC, and Telemetry protocols, sending real-time resource data, RDMA statistics, and alarm information to data center operation platforms. This enables automated network quality tracing, fault diagnosis, risk early warning, and architecture optimization, reducing operational complexity and improving maintenance efficiency.

Security & MACsec 256-bit Encryption Features

The S9800-G Series delivers robust security protection and high reliability for mission-critical data center environments. It supports hardware-accelerated MACsec encryption with 256-bit algorithms, securing data transmission across all ports by encrypting authenticated user traffic and verifying data integrity. The switch also offers comprehensive security policies, including AAA/RADIUS authentication, IP/MAC/VLAN/port binding, anti-DOS/ARP attack mechanisms, and large-capacity ACLs (Access Control Lists) for fine-grained traffic filtering. For reliability, it features redundant hot-swappable power and fan modules, overcurrent/overvoltage/overheat protection, and automatic fan speed adjustment based on temperature—ensuring 24/7 stable operation even in harsh conditions. Fan missing protection further prevents chip damage, enhancing device durability.

Technical Specifications & Models List

Tailored for modern data center requirements, the S9800-G Series supports a full suite of data center features, including VxLAN and BGP-EVPN for network virtualization, service chain integration, and BUFFER visualization with parameter tuning. Its advanced QoS (Quality of Service) capabilities enable Layer 2-Layer 4 traffic classification based on MAC address, IP address, TCP/UDP port, protocol type, and VLAN. Each 100G port supports multiple unicast queues with flexible scheduling algorithms (SP/WRR/SP+WRR/WFQ/SP+WFQ) and CAR (Committed Access Rate) with granularity as fine as 8Kbps. The switch also supports TAP (Test Access Point) traffic distribution, enabling load balancing, tunnel encapsulation/decapsulation (GRE/NVGRE/VXLAN), and packet modification for intrusion detection, traffic analysis, and behavior auditing.

Typical Application Scenarios for Data Center

The H3C S9800-G Series offers diverse and secure management options to simplify network operation. It supports standard management interfaces (Console, USB, out-of-band Ethernet) and protocols such as SNMPv1/v2/v3, CLI, Telnet, FTP, SSH2.0, and SSL. For automated management, it integrates with H3C iMC (Intelligent Management Center) and third-party network management platforms, supporting sFlow and NetStream for detailed traffic statistics. The switch is also compatible with multiple cloud platforms, adapting to hybrid cloud and multi-cloud deployment scenarios. Features like zero-configuration Auto-config, configuration rollback, and hot patching further reduce maintenance costs and minimize downtime.

Typical Application Scenarios

  • Core/aggregation layer in large-scale data centers and AIGC intelligent computing clusters
  • High-density server/GPU cluster access in cloud computing and big data platforms
  • Lossless RoCE network deployment for HPC, AI training, and distributed storage systems
  • Spine-Leaf architecture in modern data centers requiring high redundancy and scalability
  • Mission-critical environments such as financial data centers and enterprise private clouds
